Definitions
- the invention relates to a large component for a rail vehicle.
- a skeleton structure is constructed from sheet metal profiles and planked with a sheet metal panel, with the sheet metal panel representing the outer skin of the large component.
- the resulting structure offers high strength at low weight and is equally suitable for production from steel or stainless steel.
- the skeleton structure is made up of frames and stringers oriented normal to the frames, which are usually welded to one another and to the planking. The structure constructed in this way does not sufficiently meet modern requirements for strength combined with low mass, so that optimizations of this construction were created.
- the planking can be made up of a plurality of metal sheets, each of which has different properties, so that metal sheets with a greater thickness or a different material composition are used in places with high strength requirements be provided.
- the corners of door and window cutouts require a higher level of strength that is not required elsewhere.
- the sheet metal parts mentioned are usually connected to one another by means of welding, in which case a welding process with as little heat input as possible should be selected so that there is little distortion of the components and the required finishing work, eg grinding and cementing, can be minimized. Welding processes that can be automated are particularly advantageous, whereby the accessibility of the welding point by the welding machine must be taken into account in the design.
- a frequently used welding process is spot welding, in which electric current is passed through two overlapping metal sheets and these are locally melted. This requires an overlap of the sheets, which can lead to increased mass of the large component and potential problems with the rust protection at the point of overlap.
- attachment points are provided to which these interior components can be detachably attached.
- C-rails have proven their worth here, as they allow the installation site to be precisely adjusted. The simultaneous fulfillment of different requirements for a large rail vehicle component, in particular low mass with optimal local distribution of strength, corrosion protection and automatable manufacturability with the lowest need for reworking and the integration of a C-rail cannot be achieved with measures known from the prior art. Presentation of the invention
- the invention is therefore based on the object of specifying a large component of a rail vehicle which is optimized with regard to its manufacture using laser welding and which includes a C-rail.
- a large component for a rail vehicle comprising a lattice-shaped composite of bows and frames and skins of this grid-like composite, the frames being designed as flat sheet metal parts which are butt-welded to the skin, and the bows as flat sheet metal parts are designed, which are butt-welded to the planking, with a C-rail being arranged on at least one of the bows.
- the advantage can be achieved of being able to create a planked bow wall that can be produced automatically, includes a C-rail and the individual parts of which can each be produced very easily.
- a composite of bows and frames is to be produced, with the bows and frames being designed as flat sheet metal parts.
- a flat sheet metal blank can be used in the present solution, since no overlaps are required for the production of a weld seam.
- the bows and ribs are connected to the planking butt with a so-called T-joint.
- Such a weld seam is preferably to be produced by means of laser welding, since this introduces the required energy in a very limited manner and thus the distortion of the connected components is minimal.
- the surface quality of the planking on the side facing away from the weld seam is not affected by the laser welding, so that no reworking such as cementing and grinding is required there. This is particularly advantageous as this side is generally a visible surface where great importance is attached to appearance.
- Another advantage of this process is that due to the smaller heat-affected zone, the use of work-hardened steels is preferred, since the strength of these steels is only minimally impaired.
- the bows are at least partially connected to a C-rail before assembly with the planking and the frames and connected as a common, prefabricated assembly with the frames and the planking to form a large component. It is advantageous to use a C-rail made of the same material as the bow, which is produced from sheet metal by a forming process. Typically, roll forming can be used for this.
- the bows are divided into individual bow sections, which are welded to the side of the C-rail facing away from the opening of the C-rail.
- the frames engage in the distances between the individual bow sections, resulting in a lattice structure.
- the proposed design offers excellent protection against corrosion even when using conventional, non-stainless steel, since the entire surface of all components is easily accessible and with the appropriate
- Anti-rust coating can be applied. Due to the construction from simple, flat pieces of sheet metal, there are no undercuts, into which the corrosion protection can often only penetrate inadequately. Corrosion protection measures are particularly easy to implement, especially due to the exclusive use of butt weld seams and the resulting omission of double sheet metal layers.
- Another advantage lies in the lower mass of a large component compared to a large component of the same dimensions and strength, since there are no double layers of sheet metal to produce weld seams.
- a preferred embodiment of the invention provides for the planking to be constructed from a plurality of metal sheets which have different material compositions or thicknesses. Such can be locally increased
- Strength requirements for example on window corners or the connection of door pillars, are taken into account without having to provide this increased strength in places without this need. It is essential to design the outer skin of the large component step-free, the different sheet metal thicknesses are to be taken into account on the inside of the planking by dimensioning the bows and frames accordingly.
- the large component according to the invention can be used particularly advantageously as a side wall of a rail vehicle, since the specific advantages, in particular the integration of a C-rail, particularly come into play.
- interior fittings such as seats, partition walls, handrails, etc. are usually attached to the side walls.
- It can also be used as an end wall or roof, since other assemblies such as ventilation ducts, roof panels or ticket machines often have to be attached to these.
- a C-rail to the large component in the manner indicated and to arrange it below a window frame and to equip it with water inlet holes and water drainage holes.
- the water inlet holes are to be provided in the installation position above the attachment to the bows on the base of the C-profile. In this way, water that has penetrated through the window seals can be caught at a predetermined point and directed away so that it does not reach other parts of the side wall structure.
- the drain from the C-rail is via Water drainage holes, which are located on the underside of the C-rail (in the installed position) at those points where safe water drainage is guaranteed.
- Fig.3 Large component oblique view.
- Fig.l shows an example and schematically a large component of a rail vehicle in a sectional view.
- a highly abstracted section through a large component 1 in the form of a side wall is shown, which is manufactured in a differential construction.
- This large component 1 is made up of planking 4 and a framework of bows 2 and ribs 3, with the section shown running between two ribs 3 in the vertical direction.
- the frames which are vertically oriented in the installation position
- FIG. 2 shows, by way of example and schematically, a large component of a rail vehicle in a view of the supporting structure made of bows and frames.
- the abstracted example from FIG. 1 is shown in the view from the inside of the large component, with the bows 2 being covered by the C-rail 5 .
- the bows 2 do not touch the frames 3 and are also not welded to them.
- the C-rail 5 is connected to the frames 3 by means of a weld seam 7 .
- the laser welding process enables the exact positioning of such a weld seam with a very small spatial extent.
- FIG. 3 shows an example and a schematic of a large component of a rail vehicle in an oblique view.
- a section of a large component 1 of a rail vehicle is shown in an oblique view from the inside, which forms a side wall with two window cutouts.
- the large component 1 comprises a supporting structure made of bows 2 and frames 3, with 2 C-rails being arranged on the bows.
- the frames 3 are tightened between the window gaps to reduce deflection of the side wall.
- three C-rails 5 are provided below the window cutouts, which can be used, for example, to attach seats.
- the same principle underlying the invention can also be used in a roof, for example for the attachment of Cable trays or air conditioning ducts or in a bulkhead.
- FIG. 4 shows a detail of the large component of a rail vehicle from FIG. 3 as an example and schematically.
- the bearing of the C-rail 5 on a frame 3 is shown, with the shape of the outer contour of the frame 3 ensuring that the C-rail 5 is positioned exactly. In this way, a weld seam can connect the C-rail 5 to the frame 3 exactly.
